1 From: Stretch to See: Lateral Tension Strongly Determines Cell Survival in Long-Term Cultures of Adult Porcine Retina Invest. Ophthalmol. Vis. Sci ;54(3): doi: /iovs Figure Legend: Immunohistochemical labeling of ganglion cells and rod photoreceptors using NeuN and rhodopsin. At 2 DIV, stretch-cultured explants show numerous NeuN-labeled cells of ganglion appearance in the GCL (A). Corresponding standard and free-floating culture specimens show scattered labeled cells in the GCL (B, C). At 5 DIV, stretch-cultured specimens display many labeled cells of ganglion cell appearance in the GCL (D). Standard cultures at the same time point show scattered labeled perikarya, as well as scattered structures in the inner part of the specimen (E). Free-floating cultures display very weak labeling of isolated cell-like structures located randomly throughout the specimen (F). At 10 DIV, stretch-cultured explants show many labeled cells in the GCL, although they appear to be fewer than at 2 and 5 DIV (G). Corresponding standard cultures show strong labeling of unidentifiable structures at the inner border of the specimen (H). Specimens cultured free-floating show very few, isolated, weakly labeled cell-like structures at random locations in the specimen (I). Rhodopsin labeling of 2 DIV cultures revealed stretch-cultured explants as having well-preserved inner and outer segments as well as a clearly defined ONL (J). Standard-cultured specimens display strongly labeled remnants of outer segments in the outermost part of the specimen, as well as weakly labeled perikarya in the ONL (K). Free-floating cultured explants show strong labeling of cell bodies localized to the ONL, the overall morphology of which appears disrupted (L). At 5 DIV, stretch-cultured specimens show strong labeling of both rod cell bodies and inner and outer segments (M). Standard-cultured explants display very weak labeling of cell bodies in the ONL, with slightly stronger labeling of what appears to be remnants of photoreceptor inner and outer segments in the outermost part of the specimen (N). Free-floating cultured specimens show strong labeling of rod photoreceptor cell bodies in what appears to be a very disrupted ONL (O). At 10 DIV, stretch-cultured specimens show strong labeling of rod outer segments, with weaker labeling of inner segments and cell perikarya (P). Standard-cultured explants display labeling of disorganized structures in the outermost part of the specimen (Q). Free-floating cultures display labeling of small isolated structures scattered throughout the specimens (R). Scale bar: 50 μm.
